Acoustic Navigation Aid for Autonomous Miners

Miners today use externally powered machines designed to be used by a single operator, the autonomous miner. Many companies offer computer-operated mining equipment that can be used for both high wall and underground applications. Programmable logic controls with ring laser gyroscopes and inclinometers are utilized to enable miners to follow prescribed paths in a coal seam with accuracy. Because of this technology, miners may be positioned in nonhazardous locations as they steer the mining equipment.
